550 Mustang: We add Safety, Suspension, Hoosiers and go to NASA Nats!

We had a very busy September and managed to squeeze in a little development work and parts installation onto our 2018 Mustang GT test mule, which we cover in great detail in our S550 Forum Build Thread.

The changes we made in the week before the 2018 NASA National Championship event at Circuit of the Americas (COTA) were huge, and it helped us make a leap forward in on-track performance.

We added a new 4-point roll bar we built, a seat bracket kit we designed, a Sparco Circuit II seat, and Scroth harnesses for safety.
